[Where control sites are used for the baseline, the emissions and removals in control sites shall be measured at the same time as in the permanent sample plots;] The identification of all potential [causes and] sources of, and the collection and archiving of data on, [monitored][ positive and negative] leakage [outside the project boundary which is significant and reasonably attributable to the project activity] during the crediting period [and all relevant data necessary for demonstrating that [negative] leakage has been prevented by the project design]; The collection and archiving of all [information] relevant [for the provisions of paragraph 16 (c) above] [data necessary for [the analysis of] [monitoring] [the socio-economic and] environmental impacts of the afforestation or reforestation project activity [and any remedial measures implemented as part of the project activity]]; [[Collection of information on] the implementation of the measures to minimize the risk of non-permanence of the afforestation or reforestation project activity;] [Collection of transparent and verifiable information to demonstrate that each carbon pool that the project participants have chosen not to account for is not a source, and that emissions of each gas excluded from the baseline net greenhouse gas removals by sinks have not increased;] [Changes in circumstances within the project boundary that affect legal title to the land, rights of access to the carbon pools, or the status of the net anthropogenic greenhouse gas removals by sinks;] Quality assurance [and quality control procedures] for the monitoring process; Procedures for the periodic calculation of the net anthropogenic greenhouse gas removals by sinks due to the afforestation or reforestation project activity and documentation of all steps involved in those calculations [including procedures to factor out removals from natural and indirect effects], [and for the periodic review of implementation of activities and measures for the limitation and/or prevention of [negative] leakage].
i) Procedimientos para el cálculo periódico de las absorciones antropógenas netas de gases de efecto invernadero por los sumideros debidas al proyecto de forestación o reforestación y documentación de todos los pasos de esos cálculos [incluidos los procedimientos para excluir las absorciones debidas a efectos naturales e indirectos], [y para el examen periódico de la ejecución de actividades y medidas para la limitación y/o prevención de las fugas [negativas]].
